A cleaner opens the site cupboard before the first shift and finds a spray bottle with no readable name. Nobody can match it to a task or product document. A cleaning business COSHH assessment starts by stopping that bottle from reaching the work area.
A cleaning business COSHH assessment must connect the container in the cleaner’s hand to an approved task, surface, room and handling method. Build that connection before mobilisation. Do not leave the decision to the cleaner at the cupboard door.
Set the work boundary before choosing chemicals
Start with the work you sold. List the rooms, tasks and exclusions from the accepted quote or contract. Then choose products for that work.
Do not start with a company-wide product list. A product used safely on another site is not automatically approved for this one. The surface, application method, storage point and people nearby may be different.
Copy the contracted tasks into the site record
Write one clear line for each task and area. Name the surface where it matters.
“Clean washrooms” is too loose. Separate the floor, sanitary fittings, partitions, mirrors and touchpoints if they use different products or methods. Record restricted rooms and areas that need permission or an escort.
Mark what is excluded. If the cleaner has not been authorised to remove limescale from a specialist finish, do not let a casual client request add that task during the shift.
Set these boundaries while building the commercial cleaning contract scope and site survey. The chemical record depends on an agreed description of the work.
For one-off property work, use an end-of-tenancy cleaning scope with labour and exclusions to separate the accepted clean from extra treatments discovered after access.
Name the surface and application method
Record how the product reaches the surface. A spray, measured solution, wipe and machine application can create different working conditions even when the product name stays the same.
Do not invent a method from habit. Read the current label, safety data sheet and manufacturer instructions. Match those instructions to the actual surface and task.
If the product information does not cover the intended use, hold the task. Change the product or method after a proper review.
Mark who supplies each product
Label every product as supplied by your business or supplied by the client. Client ownership is not approval.
A client-supplied product still needs an identifiable container, current product information, an approved task and a storage point. If those pieces are missing, keep it out of the active work.
Walk the site before completing the record
Inspect the building before releasing the crew. A task list will not show a blocked water point, an occupied corridor or a cupboard shared with unidentified containers.
Walk the route from storage to the work area. Check how the cleaner carries the product, prepares it, uses it and returns it.
Check the working conditions
Record the following where they affect the task:
- The exact storage cupboard, cabinet or room
- Water access and preparation points
- Ventilation available during the work
- Waste and spill arrangements
- Storage conditions and separation required by the current label and safety data sheet, including identified incompatibilities
- Occupied rooms and adjoining public areas
- People who may enter while the product is in use
- Damaged containers, missing labels or leaking closures
Do not write “stored on site”. Name the location. If two cupboards look alike, add a plain description or site photo to the controlled record.
Record people and activity nearby
Check who may be exposed while the task is under way. That can include cleaners, client staff, visitors, residents and other tradespeople.
Write a direct instruction for changing conditions. If staff or visitors enter an area that was meant to be empty, tell the cleaner whether to stop, secure the product and call the supervisor.
The same product may need a different decision when the room, quantity, application method or people nearby change. Assess what happens on this site, not what normally happens elsewhere.
Write the stop-work triggers
Give the crew visible reasons to stop. Include an unreadable label, an unknown bottle, a different product, damaged packaging, a changed task or an occupied area that conflicts with the approved method.
Name the person the cleaner must contact. “Ask the office” is not enough during an early shift or locked-site visit.
Build the cleaning chemical register
The cleaning chemical register answers one question: which products are currently controlled at this client site?
It is not the assessment. The register identifies the product and links it to the task, documents and status. The assessment explains how a substance hazardous to health is used and what controls apply to that use.
The register may cover all controlled cleaning products kept or used at the site. COSHH assessment duties concern substances hazardous to health, so use the regulator guidance for the job location to decide which products and tasks need assessment. Give each controlled product its own clear register entry.
Record what the cleaner needs to match
For each product, record:
- Product name and identifying details
- Contractor-supplied or client-supplied status
- Approved task, surface and room
- Original or approved secondary container
- Exact storage point
- Current label and manufacturer instruction reference
- Safety data sheet status and, when available, its reference and revision identifier
- Assessment reference where COSHH applies to the task
- Person who approved the entry
- Crew briefing status
- Product status: active, held, removed or replaced
Check the label and supplier information to establish whether a safety data sheet is required. Record an available sheet with its reference. If the product does not require one, record the basis and evidence checked. If a required sheet is missing, mark the product as held and check the official HSE or HSENI requirement before use.
Keep the active list short. Move superseded entries out of the working pack while retaining them in the change history.
A cleaner should be able to compare the bottle with the register and get a clear answer. If the match depends on guessing what somebody poured into a spray bottle, the product is not ready for use.
Complete the cleaning business COSHH assessment by task
Start with the substance and the work being done. Record the product, task, surface, room, amount and application method. Then identify who may come into contact with it and how that contact could happen.
The cleaning business COSHH assessment turns product information into a site decision. A safety data sheet describes the product. It does not approve a specific cleaner using that product on a specific surface in an occupied building.
Choose the regulator by job location before completing the assessment. For work in England, Scotland or Wales, check the current process with the Health and Safety Executive (opens in a new tab); for work in Northern Ireland, check the Health and Safety Executive for Northern Ireland COSHH guidance (opens in a new tab).
Use current product information
Read the label, safety data sheet when required and available, and manufacturer instructions. Record the document reference beside the evidence you take from it.
Extract each point and turn it into a site instruction:
- Hazards: state what the cleaner must avoid and which task creates the risk
- Exposure routes: state how contact could happen during preparation, use or clean-up
- Incompatible products: name the separation or stop instruction from the product information
- Preparation: state the approved preparation point and method
- Use: state the surface, application method and work-area controls
- Storage: name the container condition and exact return point
- Spills: point to the site response and the person to contact
- First aid: point to the current product instruction and emergency contact
- Disposal: state the approved site route from the product and site information
Do not copy a dilution from an old assessment or transfer instructions from a similar-looking product. If required product information is missing or unclear, hold the product.
Record where the cleaner can access the documents during the shift. A file held only at the office does not help when the site supervisor is standing in front of the cupboard.
Select controls for the real task
Work down the control hierarchy. Remove the need for the product where you can. If that is not practical, consider a safer substitute, then reduce exposure by changing the amount or application method before relying on personal protective equipment.
Next, separate people from the task and use the ventilation, access controls or other site measures selected for the work. Record personal protective equipment after those decisions, not instead of them.
Ask a competent person to decide whether exposure monitoring or health surveillance is needed. Record the decision, basis, name and date. Hold the affected task while that decision is pending.
Finish with a decision. Approve the task, change the method or hold the product.
Use a copy-ready assessment record
Keep a task record for each substance hazardous to health and use that needs its own controls. A product used for two different methods may need separate task entries.

Turn the assessment into a chemical handling checklist
The assessment is the decision record. The chemical handling checklist is the cleaner’s job-order instruction.
Keep it brief enough to use at the cupboard and work area. Follow the order of the shift.
Before use
Tell the cleaner to:
- Match the container to the active register entry
- Check the label is readable and the container is sound
- Confirm the task, surface and room
- Read the approved application instruction
- Check that the work area matches the recorded conditions
- Stop if the product or task is different
During use
State the approved method. Include any access control or work-area instruction selected in the assessment.
The checklist must not invite improvisation. A cleaner should not change the amount, method, surface or product because the job is taking longer than expected.
If somebody enters a controlled area, follow the stop instruction. Secure the product and contact the named supervisor rather than trying to negotiate around the change.
After use
Tell the cleaner how to close the container, check for damage and return it to the named storage point. Include the reporting route for a missing label, leak, spill or empty container.
Do not let bottles collect in vans or move between sites without control. The register applies to the named site and approved task.
Build the COSHH mobilisation pack
Before mobilisation, build one indexed pack containing:
- The contracted tasks, rooms and exclusions
- The active cleaning chemical register
- The task-level COSHH assessments
- The current safety data sheets and product instructions
- The chemical handling checklist
- The crew briefing record
- The change log and current issue reference
Keep one unmistakable current version in the crew pack. Store superseded versions in the office history.
Do not release the first shift until the wider site safety records are current, accessible to the crew and matched to the site. Check the site risk assessment, emergency and first-aid arrangements, training and competence records, access controls, key and alarm instructions, and any task-specific records required for the equipment or work. Hold the affected task if one of those records is missing or belongs to another site.
Give each safety record its own document type, owner, version and access controls, even when it shares the same client or site reference as the quote, invoice or job record.
Brief the crew before releasing the shift
Show the cleaners the actual containers, storage point and work areas. Do not brief from the office if the site layout is what controls the work.
Ask each cleaner to explain the stop-work triggers back to the supervisor. Correct any gap before the shift starts.
Record the briefing date, attendees, person giving the briefing and document version. That record shows which instructions the crew received. It also tells you who needs another briefing after a change.
Release only the tasks that have a matched product, completed assessment and current checklist. Hold the rest.
Control unknown bottles, client products and substitutions
An unmarked bottle is not a puzzle for the cleaner to solve. Do not ask anyone to identify it by smell, touch or a test application.
Stop the affected task. Keep people away from the issue and follow the site escalation and emergency arrangements. Record where the container was found and who took control of the response.
Review a client-supplied chemical before adding it to the active register. Confirm its identity, documents, intended task, surface, method and storage point. A request from the client does not bypass the assessment.
Treat a substitute as a new product check. Its hazards, instructions and surface limits may differ from the usual product. Mark the old entry as removed or replaced, assess the substitute and brief the affected crew before restarting.
Update the record when the job changes
Set a planned review date or review frequency and give the review to a named owner. The owner must review the cleaning business COSHH assessment regularly, immediately after a material change and whenever there is reason to think it may no longer be valid. Do not invent a universal annual deadline.
A task approved for an empty washroom may not remain approved when staff and visitors are using the adjoining corridor. Stop and reassess the working conditions rather than treating occupancy as a minor inconvenience.
Carry unresolved chemical-control issues into the next commercial cleaning site review and issue log. Give each issue an owner and decision date. Do not bury it in general client notes.
